pubmed:abstractText |
C3H mice are highly susceptible to the Brazil strain of Trypanosoma cruzi. These mice usually die during the acute phase of infection and develop a profound immunosuppression to heterologous and parasite antigen. In this study, we confirmed earlier reports that infected mice maintained at elevated environmental temperature (36 degrees C) are significantly more resistant to T. cruzi than are mice kept at 20 to 24 degrees C. To determine whether the benefits of increased environmental temperature were due to alterations in the host immune system, the production of antibody to heterologous antigen and the development of parasite-specific T-helper cells were examined in noninfected and T. cruzi-infected mice. Mice were immunized with either sheep erythrocytes (SRBC) or trinitrophenyl groups (TNP) conjugated to fixed culture forms of T. cruzi, and the splenic direct plaque-forming cell (DPFC) responses to SRBC and to TNP-conjugated SRBC were determined. The DPFC response to SRBC from infected mice maintained at elevated environmental temperature was much higher than the suppressed response of infected mice held at room temperature and slightly higher than the response of age-matched noninfected control mice. Likewise, maintaining infected mice at 36 degrees C significantly enhanced the parasite-specific responses of T-helper cells, as reflected by anti-TNP DPFC responses of mice immunized with TNP-conjugated TC.
